单击按钮的Chrome扩展程序

Question

I have a page with a button and I'm creating a chrome extension to click on it but it doesn't work:

<input type="submit" name="commit" value="add to basket" class="button"/>

This is my manifest.json

{
    "description": "Click",
    "manifest_version": 2,
    "name": "click-product-addtocart-button",
    "version": "0.1",

    "permissions": [
        "activeTab"
    ],

    "background": {
        "scripts": [
            "background.js"
        ]
    },

    "browser_action": {
        "default_icon": {
            "32": "/images/icons/16.png"
        },
        "default_title": "Click product"
    }
}

and this is my background.js

chrome.browserAction.onClicked.addListener(function(tab) {
    chrome.tabs.executeScript(tab.id, {
        code: "document.getElementByName('commit')[0].click();"
    });
});

I click on the app but nothing happens. I have tried several things but that seems not to work

Your manifest must request permission to access the current page by URL as well as just the current tab. Update your permissions to the following:

"permissions": [
     "activeTab",
     "*://*/*"
],

This will allow the extension to access any page. I would also recommend changing name to id . This will prevent any confusion in the future. You would do this as follows:

<input type="submit" id="commit" value="add to basket" class="button">

Then for background.js:

chrome.browserAction.onClicked.addListener(function() {
    chrome.tabs.executeScript({
        code: "document.getElementById('commit').click();"
    });
});

You'll notice I also removed the specificity of the tab that you had in your question. This is not necessary.
